Description
본 발명은 고댐핑성이 향상된 부시 고무 조성물에 관한 것이다.The present invention relates to a bush rubber composition with improved high damping properties.
기존의 자동차용 부시 고무(bush rubber)는 생산 직후의 초기 내구성능만을 중요시하여 고무가 사용되는 환경에 따른 노화현상에 의한 재료의 경시변화를 무시한 개발을 진행하여 왔다. 이에 따라 차량의 사용년수 증가에 따른 고무의 경화현상 발생으로 스프링 특성이 초기 튜닝값에 비해 증가되어져 노면으로부터의 진동을 바로 승차자에게 전달시키는데, 이는 노화에 따른 가교 절단으로 인한 고무의 크랙(crack) 발생으로 안락감을 저하시키는 문제를 야기시켰다.Existing automotive bush rubber has been developed to ignore the aging change of the material due to the aging phenomenon according to the environment in which the rubber is used, focusing only on the initial durability performance immediately after production. As a result of the hardening of the rubber due to the increase in the number of years of use of the vehicle, the spring characteristics are increased compared to the initial tuning values, and the vibrations from the road surface are immediately transmitted to the passengers. Development has caused a problem of lowering comfort.
또한, 자동차 환경규제에 따른 배기 머플러 주위의 온도 상승으로인해 70 ℃ 분위기에서 장시간 노화물성을 개선하기 위한 연구개발이 주를 이루어왔다. 이에, 차량 주행 중 요철과 같은 둔턱을 통과할 때 대변위 진동에 대한 차량 주행 승차감을 향상시키기 위해 고댐핑성(high damping) 성능 서스펜션 부시 조성물 개발이 요구되어왔다. 그러나, 오늘날 부시고무에 요구되는 노화물성, 내피로성능 및 고댐핑성을 동시에 만족하는 재질은 없는 상황이다.In addition, due to the increase in the temperature around the exhaust muffler according to the environmental regulations of automobiles, research and development has been focused on improving the aging property for a long time in the 70 ℃ atmosphere. Accordingly, there has been a demand for the development of a high damping performance suspension bush composition to improve the riding comfort of the vehicle against large displacement vibration when passing through a barrier such as unevenness while driving the vehicle. However, there is no material that satisfies the aging resistance, fatigue resistance and high damping resistance required for bush rubber today.
이에, 본 발명자들은 상기와 같은 점을 감안하여 연구 노력한 결과, 천연고무, 스티렌부타디엔 고무, 황, 촉진제, 활성화제, 노화방지제, 분산제, 프로세싱 오일 및 카본블랙을 특정 함량 사용 함으로써 부시 고무 조성물을 완성하게 되었다.Accordingly, the present inventors have conducted research in view of the above, as a result, using a specific amount of natural rubber, styrene butadiene rubber, sulfur, accelerator, activator, antioxidant, dispersant, processing oil and carbon black to complete the bush rubber composition Was done.
따라서, 본 발명은 노화물성, 내피로성능 및 고댐핑성능이 향상된 부시 고무 조성물을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a bush rubber composition having improved sinterability, fatigue resistance and high damping performance.
본 발명은 천연고무 60 ~ 80 중량부 및 스티렌부타디엔 고무 20 ~ 40 중량부를 포함하는 원료고무 100 중량부에 대하여, 가교제인 황 1.5 ~ 2.5 중량부, 촉진제 1.3 ~ 2.0 중량부, 활성화제 8 ~ 15 중량부, 노화방지제 5 ~ 10 중량부, 분산제 1 ~ 3 중량부, 프로세싱 오일 5 ~ 10 중량부 및 카본블랙 20 ~ 50 중량부를 포함하는 고댐핑성 부시 고무 조성물을 그 특징으로 한다. The present invention is based on 100 parts by weight of raw rubber including 60 to 80 parts by weight of natural rubber and 20 to 40 parts by weight of styrene-butadiene rubber, sulfur 1.5 to 2.5 parts by weight of crosslinking agent, 1.3 to 2.0 parts by weight of accelerator, 8 to 15 It is characterized by a high damping bush rubber composition comprising parts by weight, 5 to 10 parts by weight of antioxidant, 1 to 3 parts by weight of dispersant, 5 to 10 parts by weight of processing oil and 20 to 50 parts by weight of carbon black.
본 발명에 따른 고댐핑성 부시 고무 조성물은 기존의 부시 고무 조성물에 비해 내열성, 제품 피로성능 및 고댐핑성능이 월등히 향상되었다.The high damping bush rubber composition according to the present invention has significantly improved heat resistance, product fatigue performance and high damping performance compared to the conventional bush rubber composition.
이와 같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 천연고무, 스티렌부타디엔 고무, 황, 촉진제, 활성화제, 노화방지제, 프로세싱 오일 및 카본블랙을 특정 함량 포함하는 고댐핑성 부시 고무 조성물에 관한 것이다.The present invention relates to a high damping bush rubber composition comprising a specific amount of natural rubber, styrenebutadiene rubber, sulfur, accelerators, activators, antioxidants, processing oils and carbon black.
상기와 같은 목적을 달성하기 위한 본 발명의 고댐핑성 부시 고무 조성물에 대하여 상세히 설명하면 다음과 같다.Referring to the high damping bush rubber composition of the present invention for achieving the above object in detail as follows.
본 발명에서 사용되는 상기 원료 고무는 기계적 하중에 대한 피로성능이 우수한 천연고무와 댐핑성능이 우수한 스티렌부타디엔 고무를 혼합하여 사용한다. 이때, 천연고무와 스티렌부타디엔 고무는 60 ~ 80 : 20 ~ 40 의 중량비로 혼합하는 것이 바람직하며, 이와 같은 함량비로 제조된 원료고무의 100 중량부는 다른 성분들의 함량 기준이 된다. 상기 천연고무와 스티렌부타디엔 고무의 중량비가 상기의 범위를 벗어나면 피로성능 또는 댐핑성능이 저하될 수 있다.The raw material rubber used in the present invention is used by mixing a natural rubber having excellent fatigue performance against mechanical load and styrene butadiene rubber with excellent damping performance. At this time, the natural rubber and styrene butadiene rubber is preferably mixed in a weight ratio of 60 ~ 80: 20 ~ 40, 100 parts by weight of the raw material rubber prepared in such a content ratio is based on the content of the other components. When the weight ratio of the natural rubber and styrene butadiene rubber is out of the above range, fatigue performance or damping performance may be reduced.
천연고무에 고무를 경화시키고 고무의 기계적 성질을 나타내기 위해 가교제를 결합시키는데, 이를 가교공정이라 한다. 상기 가교제로 황, 촉진제 및 활성화제를 사용하였다. 본 발명에서는 피로성능이 유리한 CV(Conventional vulcanization) 황가교 시스템을 적용하였으며, 이들의 함량은 상기 원료고무 100 중량부에 대하여, 황 1.5 ~ 2.5중량부, 촉진제 1.3 ~ 2.0 중량부 포함하는 것이 바람직하다. 상기 황의 함량이 1.5 중량부 미만이면, 고무의 내구성이 저하될 수 있고, 2.5 중량부를 초과하면 사용 한계온도에 대한 내열성을 만족시키지 못하는 문제점이 발생할 수 있다. 상기 촉진제의 함량이 1.3 중량부 미만이면, 가류시간이 너무 길어 생산성이 저하될 수 있고, 2.0 중량부를 초과하면 스코치(Scorch)가 발생하여 공정 불량이 발생할 수 있다. 본 발명에서는 상기 촉진제로N-싸이클로헥실벤조티아졸-2-설펜아마이드(CZ), 테트라메틸티우람 디설파이드(TT) 2 종을 혼합하여 사용하는 것이 바람직하다.In order to cure the rubber in natural rubber and to exhibit the mechanical properties of the rubber, a crosslinking agent is combined. This is called a crosslinking process. Sulfur, accelerators and activators were used as the crosslinkers. In the present invention, a CV (Conventional vulcanization) sulfur crosslinking system having favorable fatigue performance was applied, and the content thereof is preferably 1.5 to 2.5 parts by weight of sulfur and 1.3 to 2.0 parts by weight of sulfur based on 100 parts by weight of the raw material rubber. . If the sulfur content is less than 1.5 parts by weight, the durability of the rubber may be lowered, and if it exceeds 2.5 parts by weight, there may be a problem that does not satisfy the heat resistance to the limit temperature of use. If the content of the accelerator is less than 1.3 parts by weight, the vulcanization time is too long, the productivity may be lowered. If the content of the accelerator is more than 2.0 parts by weight, the scorch (Scorch) may occur to cause a process failure. In the present invention, it is preferable to use N-cyclohexylbenzothiazole-2-sulfenamide (CZ) and tetramethylthiuram disulfide (TT) in combination as the accelerator.
상기 황과 촉진제의 중량비는 1 : 1 ~ 1.5가 바람직하며, 중량비가 1 : 1를 미만이면 가류시간이 길어져 생산성이 저하되는 문제가 발생할 수 있고, 1 : 1.5를 초과하면 스코치와 같은 문제가 발생할 수 있으므로 상기의 범위가 바람직하다.The weight ratio of the sulfur and the accelerator is preferably 1: 1 to 1.5, if the weight ratio is less than 1: 1 may cause a problem that the longer the vulcanization time, the lower the productivity, if the ratio exceeds 1: 1.5 may cause problems such as scorch The above range is preferable because it can.
또다른 가교제 성분 중 하나인 상기 활성화제는 촉진제를 활성화하는 기능을 하며, 상기 천연고무 100 중량부에 대하여 8 ~ 15 중량부 포함하는 것이 바람직한데, 활성제의 함량이 8 중량부 미만이면 가교반응이 느려질 수 있고, 15 중량부를 초과하면 가교반응이 너무 빨라져 생산성에 문제가 발생할 수 있다. 이와 같은 촉진제로는 방진고무 제조시 통상적으로 사용되는 것은 제한없이 사용할 수 있으며, 그 중 스테아르 산(stearic acid)과 산화아연이 바람직하다. 본 발명의 고댐핑성 부시 고무 조성물의 또다른 구성 성분인 상기 노화방지제는 산화방지를 위해 사용하며 N-페닐-N-아이소프로필-p-페닐렌디아민 및 2,2,4-트리메틸-1,2-디하이드로퀴놀린을 혼합하여 사용한다. 이와 같은 노화방지제는 전체 원료고무 100 중량부에 대하여 5 ~ 10 중량부 함유하는 것이 바람직한데, 노화방지제의 함량이 5 중량부를 미만이면 노화성능이 저하될 수 있고, 10 중량부 이상이면 고무배합 원가상승으로 가격 경쟁력이 떨어진다.The activator, which is one of the other crosslinking agent components, functions to activate the accelerator, and preferably includes 8 to 15 parts by weight based on 100 parts by weight of the natural rubber. It may be slow, and if it exceeds 15 parts by weight, the crosslinking reaction may be too fast, which may cause a problem in productivity. As such accelerators, those conventionally used in the production of anti-vibration rubber may be used without limitation, and stearic acid and zinc oxide are preferable. The anti-aging agent, which is another constituent of the high damping bush rubber composition of the present invention, is used for anti-oxidation, and N-phenyl-N-isopropyl-p-phenylenediamine and 2,2,4-trimethyl-1, 2-dihydroquinoline is used in combination. Such anti-aging agent is preferably contained 5 to 10 parts by weight based on 100 parts by weight of the entire raw material rubber, if the content of the anti-aging agent is less than 5 parts by weight, the aging performance may be lowered, if 10 parts by weight or more rubber compounding cost Rising prices deteriorate.
상기 분산제는 충진제를 효과적으로 분산시키기 위해 첨가하며 원료고무 100 중량부에 대하여 1 ~ 3 중량부 포함하며, 함량이 1.0 중량부 미만이면 카본블랙의 분산효과가 저하될 수 있고, 3.0 중량부를 초과하면 재료의 기계적 초기 및 노화물성이 떨어지는 문제점이 발생할 수 있다.The dispersant is added to effectively disperse the filler and contains 1 to 3 parts by weight with respect to 100 parts by weight of the raw rubber. If the content is less than 1.0 part by weight, the dispersing effect of carbon black may be lowered. The problem of poor mechanical initial and aging properties may occur.
상기 프로세싱 오일은 고무배합시 가공성 개선을 위해 첨가한다. 이와 같은 프로세싱 오일은 전체 원료고무 100 중량부에 대하여 5 ~ 10 중량부를 함유하는 것이 바람직하며, 프로세싱 오일의 함량이 5 중량부 미만이면 가공성이 떨어질 수 있고, 10 중량부를 초과하면 기계적 물성 저하되는 문제가 발생할 수 있다.The processing oil is added to improve processability in rubber compounding. Such processing oil preferably contains 5 to 10 parts by weight with respect to 100 parts by weight of the total raw rubber, and if the content of the processing oil is less than 5 parts by weight, the processability may be lowered. May occur.
본 발명의 부시 조성물에서 충진제로 사용된 카본블랙은 ASTM(AMERICAN STANDARD TEST METHOD)에 입자크기에 따라 슈퍼 어브레이션 퍼나스(Super Abrasion Furnace, SAF), 인터메디에이트 슈퍼-어브레이션 퍼나스(Intermediate Super-Abrasion Furnace, ISAF), 하이 어브레이션 퍼나스(high abrasion furnace, 이하 HAF, 패스트 익스트러딩 퍼나스(fast extruding furnace, 이하 FEF, 제너럴 퍼포즈 퍼나스(General Purpose Furnace, GPF), 세미 레인포싱 퍼나스(semi reinforcing furnace, SRF), 파인 써멀(Fine Thermal, FT) 및 미디움 써멀(Medium Thermal, MT)로 분류되는데, 본 발명에서는 카본블랙 HAF와 FEF를 사용하였다.Carbon black used as a filler in the bush composition of the present invention is Super Abrasion Furnace (SAF), Intermediate Super-Abrasion Furnace (Intermediate Super) according to the particle size in ASTM (AMERICAN STANDARD TEST METHOD) -Abrasion Furnace (ISAF), high abrasion furnace (HAF), fast extruding furnace (FEF), General Purpose Furnace (GPF), semi-rainfossing Semi reinforcing furnace (SRF), fine thermal (Fine Thermal (FT)) and medium thermal (Medium Thermal (MT)) is classified into the present invention, carbon black HAF and FEF was used.
카본블랙 입자가 작으면 동특성에는 불리하나 기계적 물성이 우수하고, 반대로 카본블랙 입자가 크면 동특성에서는 유리하나 기계적 물성이 저하된다. 따라서, 본 발명에서는 피로성능에 유리한 FEF와 댐핑성에 유리한 HAF 카본블랙을 혼합하여 사용하였다.Small carbon black particles are detrimental to dynamic properties but excellent in mechanical properties. Conversely, large carbon black particles are advantageous in dynamic properties but deteriorate in mechanical properties. Therefore, in the present invention, a mixture of FEF, which is advantageous for fatigue performance, and HAF carbon black, which is advantageous for damping, was used.
